' Specification of Letters Patent. Patented Jan. 21, 1913, Application filed December 26, ions. Serial No. 469,472.

To all ac/1.0m, it may concern:

Be it known that l, LEONARD A. YOUNG, a citizen of the United States, residing at Detroit, in the county of lVayne, State of Michigan, have invented certain new and useful improvements m Spring-Seat Structures;

and i do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art' to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to spring seat struc-' tures, especially designed for use in motor vehicles, and consists in the construction and arrangement of parts hereinafter more fully set forth and pointed out particularly in the claims. v

The primary object of the invention is to provide in a spring seat structure asoft or lightpressure, the arrangement being such as to afford an increased spring" resistance when the top of the cushion is depressed a predetermined distance.

A further obj ectof the invention. is topro-.

vide a soft or spring. edged seat cushion haying the required depth of spring in the center thereof, and wherein provision is made for reducing the height of the leather facing at the front of the cushionand preventingthe buck-ling of said facing as 1s common in seats of the usual construction. I

Fig. 2- is'a; View, showing a portion of the seat'frame broken the leather covering in section and the away Fig; 3, is afrag.

Fig. 1, the seat frame omitted in Fig. 1; be ing included in Fig. 3, Fig. 4 is a frag? mentary viewin section as-on line-M of Fig. 1. Fig. 5 is a plan view of a seat structure of a modified form, the springs appearing in dotted lines. Fig. 6 is a transverse section through the spring seat structure and the seat frame, as on line 66 of Fig. 5.-

Fig, 7 is an enlarged fragmentary View in section through the seat frame, the border frames of the seat structure-and the leather Fig. 8 is a fragmentary of the seat cover. view in transverse section through one of the supporting bars ason line 8-8 of Fig. 4;

Referring to the characters of reference, 1 designates the seat frame which is usually formed of wood and is rectangular in structure. Upon the seat frame the spring seat structure is mounted, said structure in accordance with this invention consisting of the'base strips 2 and 3 attached at their ends tonthe border frames. The base strips 2 and'3 are at right angles to one another, the

strips 2' crossing between two sides of the border frame on a plane with said border frame and the top' of the seat frame, while the base strips 3 are depressed within the central opening of the seat frame consider? ably below the plane of the base strips 2, and

are provided with terminal portions 5 which extend upwardly to the top of the seat frame and thence horizontally to't he border frame 4 to the opposite sides of which they are at- 1 tached. The construction above described wherein the upper and lower series of base strips are caused to cross the frame-of the seat structure at right angles is illustrated in Figs. 1, 2 and 3. 'The'two series or sets of base strips however, may be caused to extend in'the same direction instead of crossing at rightangles, which latter structure is shownm Figs; 5, 6 and 7, wherein the upper set of base strips 2' is "arrangedto extend parallel withtlie lower set of base strips 3. The only strips in this structure which cross the b e strips are the marginal strips 6.

adj

rririg'iiow more particularly to the construction shown in Figs. 1 to 4 inclusive, the lower'border frame 4 is designed to rest upon the upper edge of the seat frame 1 and the upper-base strlpsfl of the spring seat structure are attached at their opposite ends as shown at 7, to the; border frame 4;"

and extend between opposite sides of said frame in the plane thereof, said strips havinga. central enten'dingi strengthening rib Sraisedzfr' Surface t er a Pi mfil' springs into play and increasing the spring reslstance of the cushion sufficiently to sus form registering apertures 9 through whichthe lower coils of the primary SPI'HIOS 10 are passed to firmly mount the springs The lower base strips 3 which are depressed below the top of the seat frame in the manner before described and whose termin-als are attached at 11 to opposite sides of the border frame 1, are in like manner provided with strengthening ribs 12 through which the lower coils of the secondary springs 13 are passed to mount said springs thereon;

T he border springs of the primary set 10 are connected by means of a suitable clip 14 (see Fig. 4t) to'the upper border frame 15,the intermediate springs of the primary set beingiunsupported. at their upper ends.

The springs'lS of the secondary set are mer-posed between the springs of the primary et-}.; and are entirely unsupported except at base where they are attached to the asefstrips 3. The springs of the primary supported normally by the springs of the primary set only, rendering said top soft.

A- weight- .upon the cushion however, suf-- ficient to overcome the resistance of the springs of the primary set, will depress the top of the cushion sufficiently to cause it to rest upon the upper ends of the secondary set of springs, thereby bringing said latter tain the increased weight and at. the same tilyie'atford a comfortable seat. A

It is custoinary to make the springs in seat cushions SIX nches in helght.

arrangement shown in Figs. 1 and t, two

sets of springs four inches in height are employed which are so disposed as to afford and secondary sets are of the same height In the 1 opening to about the extent the base strips protrusion of the facing which renders the cushion unsightly. Should it be desired to further reduce the height of the leather facing 17- .at the edge of t-he"cushion,'the sets of base strips upon which the springs var'emount-ed may both be depressed within the opening of the seat frame, as clearly shown in Figs. 6 and 7, wherein the lower base strips 3 are lowered still farther within the seat opening than 1n the construction show trips 2 are depressed within the seat 3 are depressed in the structure shown in Figs. 2 and 3. To accommodate this arrangement the upwardly extending end portions 5 of the strips 3 are made longer while the strips 2 are provided with upwardly and horizontally extending end portions 18 whose terminals are attached; at 19 to the border frame t. By depressing both series of base strips which form the supports for the primary and secondary sets or series of prings within the seat frame opening, a still greater reduction in the height of the leather facing 17 is made possible, as shown in Fig. 7, at the same time making possible the employment of springs of the same height as used in the construction previously described with the exception that the.

border springs .20 are shorter than the corresponding springs in the previously de scribed structure; in other respects the arrangtanent is the same as that shown in Figs. 1 to 4 inclusive, with the exception that the base strips 2 and 3 which comprise the upper and lower supporting bases or frames for the sets of springs. extend parallel instead of crossing at right angles, an arrangement which facilitates somewhatv the assembling of the parts but which 1s notabsolutely necessary to follow as the support ing strips of the upper and lower bases or frames may be made to-cross at right angles, if desired.

In the arrangement shown in Figs. 5 t0 7 inclusive the border springs 20 are mounted upon the marginal strips 2 and the marginal cross strips 6, while the primary and i secondary springs of the seat structure are "the requisite depth of spring and produce a spring seat having a soft top, at the same time making it possible to reduce'the leather facing ,17 at the front of the cushion from a height of six inches, as commonly employed, to a height of four inches or less, affording also by this structure a soft or spring edged cushion; the leather facing which extends between the lower border frame 4:. and the upper border frame 15 being secured .to said frames in any suitable manner. By reducing the height of the leather facing, the liability of the buckling of said facing after the cushionhas been in use some time, is obviated, preventing a l l r -'tion, what I claim as new and desire to selocated within the border springs, as shown.-
